On December 4th, we held a party at our lab to welcome Taichi (a new assist. prof.) and the BC3. We invited Kato-san, Mia-san and so on. A lot of dishes using potatoes (potato salad, potato cake, hot pot with tomato and tuna & potato stew) were cooked because we were given many potatoes from another lab. We ate so many potatoes! Everything was really good. We talked a lot about our own studies and our recent situation, we had a nice time.
